Melt 1/4 cup butter in a large Dutch oven over medium heat; add celery and onion, and sauté 5 minutes or until tender.
Stir in stuffing mix and remaining ingredients, stirring just until mixture is moistened. Remove 2 cups unbaked stuffing, and reserve to stuff in pork roast. Spoon remainder into a lightly greased 11- x 7-inch baking dish.
Bake, covered, at 325° for 30 to 35 minutes or until thoroughly heated. Serve stuffing with pork roast.
